OLD SAYBROOK >> The Katharine Hepburn Cultural Arts Center has an interesting little show Friday and Saturday, at least judging by the title.

“Jonatha Brooke: My Mother Has 4 Noses” is a singer-songwriter’s reflection on the time she spent caring for her Alzheimer’s-afflicted mother in New York.

As Brooke tells it in a release, “Mom was a character. In fact I’ve always thanked her on stage for all the good material. Ironically, in her last two years, she took it to a new level. She was funny, she was impossible. My only instinct: write it, sing it, tell it. It was her instinct too: Almost daily she would say, ‘Boolie,’ (my nickname) ‘That’s good! Are you getting this down? We should make a play out of it!’”

Brooke has been writing songs, making records and touring since her early days in Boston with her band, The Story. The play (and a new album of the songs) weave in and out of the time with her mother. The show will be performed at the 300 Main St. theater Friday night at 7:30 and Saturday at 2 and 8 p.m. Tickets are $35. For more information, call 877-503-1286 or visit thekate.org.
